MegaCom basic framework

[yatli]

Work in progress. We can build a lot of things upon this:

enum comserver_id_t {
  COMSERVER_EXTUI, // button input, ext screen etc.
  COMSERVER_FILESERVER, // simple FTP-ish protocol
  COMSERVER_EXTMIDI, // note in, CV out etc.
  COMSERVER_MAX,
  COMSERVER_DRAIN_INVALID = 0xFF
};

Cool. I had always wanted to replace Serial.print with something more robust. DisplayMirror mode will need to be implemented using this new protocol.

[yatli]

I've never used that mode. With the new GUI (cross platform, rest assured) in place I guess it's the time.

Thinking of putting a MC into this:

int MCDisplayServer::run() {
  // TODO external key, knobs etc. events handling
  return -1;
}

[yatli]

void MCUIServer::update() {
  megacom_task.tx_begin(COMCHANNEL_UART_USB, COMSERVER_EXTUI, 513);
  megacom_task.tx_data(COMCHANNEL_UART_USB, USC_DRAW);
  megacom_task.tx_vec(COMCHANNEL_UART_USB, (char*)oled_display.getBuffer(), 512);
  megacom_task.tx_end(COMCHANNEL_UART_USB);
}

Some progress on the UI. Decoupled the Camelotia stuff and add multiple tabs:

Debug view ready:

Display mirror ready:

Too easy.

[jmamma]

😮 Great work.

Any chance for easy .png screenshot export, and support for inverse colour mode. That's how I generate screenshots for the manual.

[yatli]

Done.

[yatli]

The OLED emulation is actually an aliasing artifact. Don't know exactly how to repro that when rendering to a PNG 😅

[jmamma]

beautiful work. thankyou

[yatli]

The framework is ready now. @jmamma What about the UI? Do we want to add it to this repo?

[jmamma]

Which UI?

[yatli]

https://github.com/yatli/MegaCom.UI ignore the README.

[jmamma]

gotcha. keep repo separate is probably better.

[yatli]

Understood.

Currently it has the following functionalities:

• File Browser (wip, only CWD, GET, LS implemented)
• Debug, with improved macros. Things like DEBUG_PRINTLN now takes arbitrarily many arguments, and printed atomically.
• Midi proxy: Midi bridge into 2 virtual midi devices.
• Display Mirror, with throttle control.

You're on macOS? Let me build a package for you.

[jmamma]

either mac or pc.

A nice little speed meter:

}

i got one PT80 at home, would be so fun to have an MC inside! :)
